Ukraine has almost 14 billion cubic metres of gas in underground storage, enough to meet its needs until December, the chief executive of state gas company Naftogaz said on Monday, according to Reuters. Ukrainian Prime Minister Arseny Yatseniuk, sitting beside Naftogaz CEO Andriy Kobolev at a news briefing, blamed the breakdown of talks in a gas pricing dispute on Russia, saying Moscow had hoped to cause Kiev problems in winter. "But it is not about gas. It is a general Russian plan to destroy Ukraine," Yatseniuk said.
